TECHNICAL FIELD

[0001] The present application relates to the technical field of power generation, in particular to a wave energy collection device for power generation of a paper folding structure. BACKGROUND

[0002] With the continuous progress of science and technology and the increasing demand for energy, developing clean and sustainable new energy technologies has become an important issue in today's society. Among the many renewable energy sources, mechanical energy is of great concern due to its wide distribution and easy access. However, traditional mechanical energy collection devices often have low energy conversion efficiency, complex structure, high cost and other problems, which limit their widespread application.

[0003] In recent years, triboelectric nanogenerator (TENG) as a new type of energy collection technology, has gradually become a research hotspot due to its simple structure, low cost, small size and other advantages. TENG is based on the coupling effect of triboelectricity and electrostatic induction, which can effectively convert mechanical energy into electrical energy. However, the existing TENG devices still need to improve the energy conversion efficiency when facing low-frequency and irregular mechanical motion. In addition, how to improve the output performance of TENG in limited space is also one of the key problems that need to be solved in current research.

[0004] Traditional TENG structures are mostly designed as planar structures, which have limited surface contact area, affecting charge transfer and output performance. Although expanding the size of TENG devices can increase the surface contact area, it will lead to an increase in device size and production cost, which is not conducive to practical application. Therefore, researchers have begun to explore spatial structure design to improve space utilization and output performance. In order to solve the above problems, the present application proposes a wave energy collection device for power generation of a paper folding structure. SUMMARY

[0005] In view of the above-mentioned shortcomings of the prior art, the present application aims to provide a wave energy collection device for power generation of a paper folding structure, which can effectively increase the surface contact area of TENG in limited space, thereby optimizing charge transfer and output performance. At the same time, the paper folding structure design is simple, easy to manufacture and integrate, has good flexibility and adaptability, and can adapt to mechanical motion of different frequencies and amplitudes.

[0006] To achieve the above-mentioned purposes and other related purposes, the present application provides a wave energy collection device for power generation of a paper folding structure, comprising a rotating disc, a translational assembly, a driving assembly, a fan-shaped column, at least one paper folding friction power generation structure and at least two moving friction power generation structures, wherein,

[0007] The rotating disc is connected with the cylinder, and the center rod of the rotating disc passes through the inside center position of the cylinder and the fan-shaped column and fixes the relative position, and the rotating disc moves relative to the cylinder.

[0008] The translation assembly is connected to the cylinder and the sector columns, and the translation assembly is connected to the rotating disk, and the translation assembly is arranged inside the cylinder and located at the intervals between the sector columns;

[0009] The driving assembly, the rotating disk is connected to the driving assembly, and the driving assembly is placed at the bottom of the cylinder;

[0010] The sector column is fixedly connected to the cylinder, and the sector groove at the bottom of the cylinder is embedded and fixedly connected to the bottom of the sector column;

[0011] At least one origami triboelectric power generation structure is disposed between the cylinder and the translation assembly, and the relative movement between the translation assembly and the cylinder drives the synchronous movement of the origami triboelectric power generation structure to generate triboelectric power;

[0012] At least two mobile friction power generation structures are arranged between the outer walls on both sides of the fan-shaped column and the outer wall of the translation component. The relative movement between the translation component and the fan-shaped column drives the synchronous movement of the mobile friction power generation structure to perform friction power generation.

[0013] In one embodiment of the present invention, the translation assembly includes a pusher and a latch, wherein:

[0014] A pusher is disposed inside the cylinder, with its bottom supported by the bottom of the cylinder and passing through the intervals between the sector columns. The movement trajectory of the pusher moves along the radial direction of the intervals. When the pusher moves to a defined position, the inner arc surface of the pusher fits into the outer annular surface of the sector column.

[0015] The latch is fixedly arranged on the top of the pushing member, and a preset distance is left between the top of the pushing member and the bottom of the rotating disk. The pushing member is limited to move in the sliding groove at the top of the rotating disk by the latch, and the pushing member moves under the drive of the rotating disk through the latch.

[0016] In one embodiment of the present invention, the driving assembly includes a buoy, a connecting rod, and a support bearing, wherein:

[0017] A buoy, which is fixedly connected to the connecting rod through a groove, and is fixedly connected to the central rod of the rotating disk through the connecting rod, and the buoy and the connecting rod move synchronously;

[0018] A connecting rod, both ends of which are fixedly connected to the grooves of the buoy through the grooves of the central rod of the rotating disk, so as to transmit the movement of the buoy to the rotating disk;

[0019] The support bearing has an inner ring fixedly connected to the central rod of the rotating disk and an outer ring fixedly connected to the groove at the bottom of the cylinder, and supports the rotating disk to rotate freely.

[0020] In one embodiment of the present invention, the radial movement of the pushing member drives the synchronous contraction and expansion movement of the origami friction power generation structure to perform friction power generation.

[0021] In one embodiment of the present invention, the origami friction power generation structure is made of a flexible material, and two polymer strips are repeatedly folded to form an origami structure, one side of which is fixed to the front arc surface of the pusher, and the other side is fixed to the inner wall of the cylinder. The origami friction power generation structure is contracted and expanded by the movement of the pusher to perform friction power generation.

[0022] In one embodiment of the present invention, the polymer strips in the origami friction power generation structure adopt a three-layer structure of copper, PET, and copper. The polymer strips include transverse polymer strips and longitudinal polymer strips. The transverse polymer strips serve as friction layers to coat a layer of friction layer material fluorinated ethylene propylene (FEP) on the copper electrode, and the longitudinal polymer strips serve as electrodes and friction layers.

[0023] In one embodiment of the present invention, the mobile friction power generation structure includes a first friction layer, a copper electrode sheet, and a second friction layer, wherein:

[0024] A first friction layer, which is fixedly provided with three intervals on the outer wall of the pushing member and moves with the pushing member;

[0025] Copper electrode sheets are fixedly arranged and spaced apart on the outer walls of both sides of the sector column;

[0026] The second friction layer is fixedly arranged on the copper electrode sheets on the outer side walls of both sides of the sector column and covers all the copper electrode sheets;

[0027] A layer of sponge rubber is provided on the outer wall of the pushing member, and a layer of PVC film is attached to the sponge rubber to form the first friction layer. Four copper electrode sheets are arranged at intervals on the outer walls on both sides of the fan-shaped column, and the copper electrode sheets serve as the electrode layers of the mobile friction power generation structure. A layer of nylon film is provided on the copper electrode sheets to form the second friction layer.

[0028] In one embodiment of the present invention, the pushing member moves in the radial direction between the fan-shaped columns, causing the first friction layer and the second friction layer to slide and rub against each other. When the first friction layer and the second friction layer are in contact, negative charges are generated on the surface of the PVC film, and positive charges are generated on the surface of the nylon film. When the first friction layer and the second friction layer move relative to each other, electrons flow between the copper electrode sheets, realizing frictional power generation.

[0029] As described above, the wave energy collection device for power generation using an origami structure according to the present invention has the following beneficial effects:

[0030] (1) The present invention utilizes the deformable nature of the origami structure to significantly increase the contact area of ​​the triboelectric nanogenerator (TENG) within a limited space, thereby enhancing charge transfer efficiency and output performance. The structure is simple in design, easy to manufacture and integrate, and possesses excellent flexibility and adaptability, enabling it to flexibly respond to mechanical motions of varying frequencies and amplitudes.

[0031] (2) The origami-structured wave energy harvesting device of the present invention utilizes the deformable nature of origami through the reciprocating motion of the propulsion element, causing the origami structure to periodically contract and expand, thereby promoting full contact and separation between the friction layers, increasing the amount of charge transfer, and thereby improving power generation efficiency. Furthermore, the compact design of the origami structure effectively reduces the size and weight of the device, enhancing its portability and deployability.

[0032] (3) The wave energy collection device for power generation using an origami structure of the present invention further enhances the energy collection efficiency. The relative movement between the first friction layer on the side of the pusher and the second friction layer on the side of the fan-shaped column can generate additional electrical energy.

[0033] (4) The wave energy collection device for power generation by origami structure of the present invention applies the ups and downs of the waves to the buoy, and the buoy and the connecting rod convert the swing into the reciprocating rotation of the rotating disk and then into the linear reciprocating motion of the pushing member. This conversion of the motion mode enables the device to adapt to the ups and downs of the waves and perform well in low-frequency water wave environments. It generates stable electrical energy output under the ups and downs and push of the waves, providing a reliable and effective solution for the effective collection and utilization of wave energy.
